Navigation link from Oil Well Detail display, returns to the default Crosby asset for Well Pad Display. Why?

I'm completing Challenge 6, and I've done all navigation links as per the instructions, similarly, for all the previous instructions. However, during my testing, I noticed that it doesn't navigate as I would expect. For example,

1- From "North Dakota Overview" Display, I click on Stanley.

2- From the "Well Pad Detail" Display for Asset "Stanley", I can see the two available wells. I click on Well48.

3- From the "Oil Well Detail" Display for Asset "Well48", I can see the information as required. I click on Well Pad Display navigation link to return the previous page.

4- The "Well Pad Detail" Display for Asset "Crosby" appears, I assume it's due to it being the first asset in the list or the asset by default. However, I would think that the asset should be "Stanley", as I have returned from the Oil Well Detail of Well48 of Stanley.

Any suggestions of where I could have gone wrong?
